I have had three of these and not one has worked anything like they should.two weer returned and exchanged (that makes 5 then really) you have to retune practically daily, it records when it want to not when you do, functions should be good but most don't work. I have had hous, days,and weeks playing with them (tring to get them to work, but not much time watching them. I have removed the hard drives and had the most fun ever smashing the rest of them in to very small pieces.
